Out of courtesy, a MUC service MAY send an out-of-room <message/>
if a user's affiliation changes while the user is not in the room;
the message SHOULD be sent from the room to the user's bare JID,
MAY contain a <body/> element describing the affiliation change,
and MUST contain a status code of 101.
